11/12+1/7

Let's calculate: $\frac{11}{12}+\frac{1}{7}$

ⓘ To add fractions, put them over the same denominator, then add the numerators. We choose $84$, the least common multiple of $12$ and $7$. Multiplying the numerator and the denominator by the same number does not change the fraction: $\frac{11}{12}+\frac{1}{7}$ = $\frac{11\times 7}{12\times 7}+\frac{1\times 12}{7\times 12}$ = $\frac{11\times 7+1\times 12}{12\times 7}$ = $\frac{11\times 7+12}{12\times 7}$

$\frac{11\times 7+12}{12\times 7}$

ⓘ Perform multiplications before additions and subtractions: $11\times 7$ = $(10+1)\times 7$ = $10\times 7+7$ = $70+7$ = $77$

ⅰ $12\times 7$ = $(10+2)\times 7$ = $10\times 7+2\times 7$ = $70+14$ = $84$

$\frac{77+12}{84}$

ⓘ The numerator and the denominator are computed before the division: $77+12$ = $89$

▶Result:   $\frac{89}{84}$

The numeric value of: $\frac{89}{84}$ is:

▷ $\approx 1.0595$
